Subject: Add EDataCapture.

EDataCapture is a GConverter that captures data until the end of the
input data is seen, then emits a "finished" signal with the captured
data in a GBytes instance.

When used with GConverterInputStream or GConverterOutputStream, an
EDataCapture can discreetly capture stream content for the purpose
of caching.
